To OP, join any farm PF run of EX content and you'll probably get your log posted at some point. Maybe if someone in your FC on their FC discord can help you? Like a lot of other say, you can ask them to run a couple of EX trials and show them your skills.
And now for the other comments on this post. For one, OP asked about joining when they had no logs available to be used. I think they meanr that it was unfair because they had no logs of prior raiding experience but groups require them to measure if the person is reliable which is fair because you don't want to waste their time. Kind of like when entry jobs irl require you to have 2-3 years of experience but you're fresh out of college.
As for parsing, the tool itself is not evil and people should really get off their high horses and saying stuff like "report them when you see it." For one, you or anyone should not police on how SE and the GMs handle their ban system. If SE catered to everytime someone gets kicked for essentially griefing their group by dying constantly and refusing to actually keep up the pace, then it would be a massive witch hunt.
Yoshi-P may say parsing is not allowed, but will watch and show streamers using them. It's grey area. He doesn't want to deal bad players complaining about not being carried through content because someone bullied them into doing the bare minimum but he certainly knows that outright banning parsers would destroy raiding as a whole. And as much as people want to say "raiding scene is a minority," then why do they make high-end content? Why is there EX, Savage, Ultimate, and Unreal? Let alone have potions, food and gearsets that increase your damage? If the game can 100% survive on being totally casual then they would have already done so, seeing as not having to design said content would lighten their dev time.
But they know the answer, they need a game with variety and raiding is a core part of the game and genre. This has been said a million times before but here we go again.
Don't harass others for playing poorly, but don't harass people for expecting the bare minimum. Don't blame the tool, blame the idiot that uses it to hurt others. Toxic elite players, the game will likely never have official parsers but toxic casuals, you will never be able to delete raiding.
Anyway OP, I hope you find a group and that you'll have a good experience raiding. It's fun with the right mindset and people.
